I believe the iwlwifi driver is providing a iwlwifi-virtual-0 thermal zone but the temperature information cannot be read, hence thermald can't read this and produces the warning. However, it was my expectation that thermald should disable reading this and hence you shouldn't see many of these warnings appear.
